TUSB5052PZ datasheet by Texas Instruments

TUSB5052PZ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the TUSB5052PZ?
  A good PCB layout for the TUSB5052PZ involves keeping the high-speed USB traces short and away from noise sources, using a solid ground plane, and placing the device close to the USB connector. TI provides a recommended layout in the datasheet and application notes.
• How do I ensure electromagnetic interference (EMI) compliance with the TUSB5052PZ?
  To ensure EMI compliance, follow proper PCB layout and shielding techniques, use a common-mode choke, and add EMI filters as needed. TI provides EMI compliance guidelines in the datasheet and application notes.
• What is the maximum cable length supported by the TUSB5052PZ?
  The TUSB5052PZ supports USB 2.0 high-speed signals up to 3 meters (10 feet) in length, but this can vary depending on the cable quality and environment. For longer cables, repeaters or active cables may be necessary.
• Can I use the TUSB5052PZ in a USB 3.0 or USB 3.2 system?
  The TUSB5052PZ is a USB 2.0 repeater and not compatible with USB 3.0 or USB 3.2 systems. For USB 3.0 or USB 3.2 systems, use a repeater specifically designed for those speeds, such as the TUSB926.
• How do I power the TUSB5052PZ, and what are the power consumption characteristics?
  The TUSB5052PZ can be powered from a 3.3V or 5V supply, and the power consumption is typically around 100mA. The device also has a low-power mode that reduces power consumption to around 10mA.
